Question 1 of 3

1. A father is teaching his son to play golf. The child performs several ball tosses as a rehearsal. Considering that there is no air resistance, which throw will have the greatest horizontal range?

B because the x and y component of the velocity are similar, indicating that the angle with respect to the x-axis is close to 45°.

D because the x-component of the velocity is greater than the y-component of the velocity, so it will move faster in the x-direction.

C because the x-component of the velocity is slightly larger than the y-component of the velocity, so the angle formed with the x-axis is smaller, causing the shot to be more horizontal.

A because the y-component of the velocity is greater than the x-component, so the flight time is longer.

2. Suppose an apple is about to fall from a tree branch. Some children playing with a baseball ball accidentally hit the apple, causing it to move as shown in the figure. It can be said, regarding the apple's acceleration that it experiences during its trajectory, it can be said that:

It varies along the trajectory because it describes a curved path.

There is insufficient information to determine acceleration behavior.

It has acceleration in the x-direction and has acceleration in the y-direction.

During the entire trajectory, it has the same acceleration.

3. Suppose you want to know the height of a cliff. What should you do?

Throw a stone at a certain angle of inclination, time the time it takes to hear it hit the ground.

Drop the stone in free fall, time the time it takes to hit the ground.

Throw the stone vertically towards the ground, time the time it takes to touch the ground.

Throw a stone horizontally, time how long it takes to hear it hit the ground.
